To sterilize a 50.0-g glass baby bottle, we must raise its temperature from 21.0°C to 95.0°C. How much heat transfer is required? The specific heat of glass is 840 J/(kg · °C).
Q2/ A 4-m-internal-diameter spherical tank made of 1.75-em-thick stainless steel (k 15 W/m °C) is used to store iced water at 0°C. The tank is located in a room whose temperature is 35°C. The walls of the room are also at 35°C. The outer surface of the tank is black, and heat transfer between the outer surface of the tank and the surroundings is by natural convection and radiation. The convection heat transfer coefficients at the inner and the outer surfaces of the tank are 80 W/m2 °C and 10 W/m2 °C, respectively. Determine (a) the rate of heat transfer to the iced water in the tank and (b) the amount of ice at 0°C that melts during a 1-h period. The heat of fusion of water at atmospheric pressure is hif 334 kJ/kg.
